Nibi Metrics
Real-time water levels, forecasts, and alerts for lakes and rivers across Canada and the US. Built on official government data.
Nibi Metrics turns raw gauge readings from official hydrometric networks into something a person standing on a dock can actually use: is the water high or low for today, which way is it moving, and how unusual is this? This page explains where every number on the platform comes from and what we do to it along the way.

About Dalhousie Lake
Dalhousie Lake - a community hub for recreation and nature.
Dalhousie Lake is a prominent feature in Ontario's Lanark region, recognized for its recreational opportunities and connection to the Central Ottawa - Mississippi watershed. This expansive lake serves as an important resource for the surrounding communities, drawing visitors for activities such as fishing, boating, and swimming.
The watershed context
Part of the Central Ottawa - Mississippi watershed, Dalhousie Lake collects water from a drainage area of approximately 1,314 square kilometres. This catchment plays a crucial role in maintaining the lake's levels and ecological health. The lake is situated near several other water bodies, such as Bennett Lake and the Mississippi River, forming a network of important aquatic ecosystems in this part of Ontario.
The region experiences a snowmelt-driven seasonal hydrology, with a characteristic freshet occurring from late April to May. During the summer months from July to September, natural drawdown takes place due to evaporation and low inflow, while early winter marks a decline as ice begins to form on the lake.
Why the data matters here
Monitoring water levels at Dalhousie Lake is crucial for understanding its health and supporting the recreational activities that depend on it. The Mississippi River gauge at the lake's outlet provides valuable data on both elevation and discharge. This data helps inform local residents and visitors about current conditions, guiding decisions around fishing, water sports, and conservation efforts.
As of today, the lake’s water level reading will be compared to the median for this date, with historical data available from the Water Survey of Canada for over 22 years. This context is essential as it allows for a well-rounded understanding of variations in water levels, providing insights beyond just the raw figure.
How this page is built
Readings come from official government gauges and are rolled into daily records: the daily mean, high and low for every day on record. Each calendar day gets its own baseline from the full history, so the level you see is compared against what this specific date usually looks like rather than an annual average.
